as it passed through the Curraghs wetlands at Ballacrye, Ballavolley and Cooilbane. A small railway siding was built in 1882 to serve the Clarks stone quarry at Ballavolley, crossing the primary A3 road at Close-e-Volley. Later renamed Quarry Bends, the line running to a small loading wharf and railway siding to the main Ramsey to St. John's railway line. Motor-sport heritage The Quarry Bends complex of bends was part of the 37.50 Mile Four Inch Course for the RAC Tourist Trophy automobile races held in the Isle of Man between 1906 and 1922. In 1911, the Four Inch Course for automobiles was first used by the Auto-Cycling Union for the Isle of Man TT motorcycle races. This included Quarry Bends and the course later became known as the 37.73 mile Isle of Man TT Mountain Course which has been used since 1911 for the Isle of Man TT Races and from 1923 for the Manx Grand Prix races. Road improvements Extensive road widening and road profiling occurred during 1984/1985 at Quarry Bends by the Isle of Man Highway and Transport Board with the removal of trees and the creation of a road-side picnic-area.
